> hit or miss What a polite way to say it. CEC and DDC-CI, are these two things that should be absolutely nailed given in terms of low level commands how simple they really are and how long they've been around, yet are thoroughly broken through and through in so many subtle ways, from broken payloads to timing issues. And even when the low level protocol is correctly implemented you can be sure that the high level behaviour of the devices is not doing what you'd want it to, with no workaround possible. e.g one device turns -all- devices on/off no questions asked, another would not allow separate configuration of being controlled vs controlling, and/or power on vs power off, a third one would disable CEC the moment you select headset audio output because it goes in the way of their MegaMagicSync+ feature (which is just CEC with a bunch of useless proprietary stuff to talk to other devices of the same brand, coz gotta "add value" and "differentiate")...
